In MatrixSSL before 4.2.2 Open, the DTLS server can encounter an invalid pointer free (leading to memory corruption and a daemon crash) via a crafted incoming network message, a different vulnerability than CVE-2019-14431. En MatrixSSL versiones anteriores a 4.2.2 Open, el servidor DTLS puede encontrar una liberación de puntero no válida (conllevando a una corrupción de la memoria y un bloqueo del demonio) por medio de un mensaje de red entrante diseñado, una vulnerabilidad diferente al CVE-2019-14431. • https://github.com/matrixssl/matrixssl/blob/4-2-2-open/doc/CHANGES_v4.x.md https://github.com/matrixssl/matrixssl/issues/33 https://github.com/matrixssl/matrixssl/releases/tag/4-2-2-open • CWE-787: Out-of-bounds Write •

MatrixSSL 4.2.1 and earlier contains a timing side channel in ECDSA signature generation. This allows a local or a remote attacker, able to measure the duration of hundreds to thousands of signing operations, to compute the private key used. The issue occurs because crypto/pubkey/ecc_math.c scalar multiplication leaks the bit length of the scalar. MatrixSSL versión 4.2.1 y anteriores, contienen un canal lateral de temporización en la generación de firmas ECDSA. Esto permite a un atacante local o remoto, capaz de medir la duración de cientos de miles de operaciones de firma, calcular la clave privada usada. • http://www.openwall.com/lists/oss-security/2019/10/02/2 https://eprint.iacr.org/2011/232.pdf https://minerva.crocs.fi.muni.cz https://tches.iacr.org/index.php/TCHES/article/view/7337 • CWE-203: Observable Discrepancy CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
